5      ==============================      ==============================
6    
7    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
8      - bug was reported by Jean-Michel and Ian Fenty
9    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
10      Needed for high-res. runs with large global files
11      to be able to limit tapelev size
12    o Changed some tests for adjoint:
13      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
14      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
15      * global_ocean.90x40x15/ back to default 3-level checkpointing
16    
17    checkpoint57p_post
18    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
19    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
20      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
21    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
22    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
23      (was already the case for dissipation with mom_vecinv,
24       and also the case for grad.PhiHyd when staggered-timeStep)
25      This will allow to put dissipation out-off the AB time-stepping.
26     Unfortunately, affects truncation error. Update output of exp. that "fails"
27      (cg2d matching number) and leave the others for later: front_relax(10),
28      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
29      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
30    
31    checkpoint57o_post
32    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
33      (2) its ready to be documented during the 20050801 DocFest
34    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
35      for ideal_2D_oce and lab_sea on linux_ia32_g77
36    o set to #undef CTRL_SET_OLD_MAXCVARS_30
37      in global1x1_tot/code_seaice_adj to access indices 32, 33
38      (worth another tag)
39    
40    checkpoint57n_post
41    o adding precip control xx_precip 32
42    o adding swflux control xx_swflux 33
43    o Replacing 10 forcing penalty cost routines by 1 generic.
44    o Implementing partitioning in time-mean and variable adjustment
45      for atmos. state.
46    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
47    o in natl_box_adjoint:
48      * updated exp 1 to 10
49        (but does not have time-mean vs. variable split results yet)
50    o updated global1x1/*_seaice_adj/
51      to incorporate latest changes
52    o enable useSingleCpuIO for mdsio vector routines
53      (applies in particular to tapelev I/O)
54    o removed inefficient K-loop in all active_file*control*.F
55    
56    checkpoint57m_post
57    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
58      and advect_cs (use EXCH-2 and standard cs-32 grid files).
59    o pkg/exch2: filling of face-corner halo regions is optional
60      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
61    
62    checkpoint57l_post
63     tag before updating tutorials (pre-release-2)
64    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
65       for output and interpolation of input fields onto model grid)
66    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
67       Affects results of exp. rotating_tank ; update output.txt.
68    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
69          and taking the square quantity and/or using a fraction-weight field.
70    o fix aim_diagnostics_init.F mate numbers.
71    o add mnc output capability to diagnostics/diagstat and update
72      our cvsignore files for the ACSII output generated
73    
74    checkpoint57k_post
75    o lab_sea now uses diagnostics package and provides a suite of
76      new EXF diagnostics output.
77    
78    checkpoint57j_post
79    o exf
80      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
81        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
82        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
83      * extended diagnostics output
84        - now includes all EXF variables
85        - hs, hl moved to common block
86        - separate S/R for diagnostics, called after ctrl vector is added
87        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
88        - EXFqnet contains true Qnet (i.e. includes qsw)
89      * updated verif. lab_sea, global_with_exf
90      * Rearranging hflux (exf_mapfields -> exf_getforcing)
91        to ensure that diagnostics sees a true EXFqnet
92    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
93    o diagnostics pkg: change pointers so that 1 diagnostic can be used
94      several times with different frequencies.
95    o mnc-ify the thsice package as requested by Daniel Enderton
96      - the monitor--MNC output needs work
97      - many attributes need to be added (most are currently blank)
98    o mnc-ify theaim_v23 package as requested by Daniel Enderton
99      - many attributes need to be added (most are currently blank)
100    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
101    o add Sadourny like discretization to the 4th.O vorticity advection scheme
102    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
103      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
104         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
105    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
106     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
107    
108    checkpoint57i_post
109    o Diagnostics package was changed: diagnostic allocation is now deactivated
110      by setting an empty file name in the namelist (used to be by setting 0 frequency)
111    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
112      add 1rst Order upwind vertical Shear.
113    o add a quick fix for A/B checkpointing in OFFLINE mode
114    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
115      end-run around the C/Fortran linking horror in eesup/src/timers.F
116    o added pkg/runclock: allows user to terminate run based on wall clock
117    o added non-hydrostatic scaling parameter: nh_am2
118    o pkg/my82: futile attempt to make results compiler-independent by adding
119      some "_d 0", etc. no effect.
120    o for mnc output, fill the 'T' coordinate var with myTime and create a
121      separate 'iter' variable for iteration count
122    o pkg/diagnostics:
123      add new capability: output of Global/Regional & per-level statistics ;
124      tested against monitor output (including land & thSIce) on various exp.
125    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
126    
127    checkpoint57h_done
128      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
129      data.diagnostics, data.gchem, data.ptracers) is done.
130    
131    o pkg/diagnostics: prepare for Global/Regional statistics.
132      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
133    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
134      and rename it: DIFFERENT_MULTIPLE
135    
136    checkpoint57h_post
137    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
138    o pkg/diagnostics: change output frequency, now in seconds (instead
139      of Nb of iterations). This requires to change data.diagnostics.
140    checkpoint57h_pre
141    
142    o in mnc, let the user create the output dir if both mnc_outdir_date
143      and mnc_outdir_num are false
144    o add fflags() to pkg/diagnostics which allows one to specify, on a
145      per-file basis, the file precision [default behavior is unchanged]
146    o added diagnostics to pkg/kpp, including computation of mixed layer
147      depth based on a temperature/density criterion
148    o updated verification/natl_box to test the new pkg/kpp diagnostics
149    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
150    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
151    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
152      not mnc -- this mistake was found by JMC and is now corrected
153    
154    checkpoint57g_post
155    o add Adams-Bashforth 3rd Order time stepping:
156      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
157      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
158    checkpoint57g_pre
159    
160    o make lambda[Theta,Salt]ClimRelax spatially varying
161      (default remains spatially uniform constant based on tau)
162    o added new control variables
163      * init. uVel, vVel, etanN
164      * lambda[Theta,Salt]ClimRelax
165    o separate masks used for ctrl_pack/unpack 'from write_grid' output
166      (suggested by G. Forget)
167    
168    checkpoint57f_post
169    o add parameter "baseTime" = model base time = time at iteration zero
170      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
171      account for baseTime shift
172    o move Coriolis arrays from PARAMS.h to GRID.h
173    checkpoint57f_pre
174    
175    o mnc-ifying the seaice package
176    o introduced an alternative length scale calculation for use in the limiting
177      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
178    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
179    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
180      as well as grad(vort3).  Made it compatible with both approximate form
181      for the cubed sphere and full form of these gradients.  Added flag
182      useFullLeith to select between approximate and full form.  
183    o add "d0" in getcon.F to reduce differences between compilers/platforms
184      update output.txt of exp. fizhi-gridalt-hs
185    o change port_rand funtion to allow to set the seed.
186    o fix obscure MNC bug involving conversion between reals and integers
187      - it caused no problems with certain (eg. gcc, ifc) compilers but the
188        new version is now more standards-compliant
189    o adjoint-related modifications
190      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
191      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
192      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
193    
194    checkpoint57e_post
195    o Adding eddy stress controls a la Ferreira et al.
196    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
197    
198    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
199      update output.txt of exp. fizhi-gridalt-hs
200    o add more "Z" dimensions and associated coordinate vars to MNC
201    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
202    o parameter calendarDumps: when set, approximate months (30-31 days) and years
203      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
204      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
205      months and years.  Requires pkg/cal.
206    o diagnostics: add pickup functionality
207      - off by default for backwards compatibility
208      - current version only uses MDSIO -- MNC will be added
209    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
210    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
211    
212    checkpoint57d_post
213    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
214    o modify verification/ideal_2D_oce so that it tests the creation of mnc
215      output from the diagnostics package
216    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
217    o make genmake2 more portable by using ".$FS" instead of ".f" for more
218      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
219    o add coordinate variables to the MNC output from the diagnostics package
220    o change MNC-flags default value: true when useMNC=TRUE
221    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
222      the ability (off by default) to read the grid information using MNC
223    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
224    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
225    o do snap-shot diagnostics at the middle of the time-interval (instead of
226      at the end).
227    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
228      new test for AIM with thSIce + slab-ocean
229    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
230    o move state variable diagnostics to the beginning of the time step ;
231      (note: still needs some work specially for snap-shot diagnostics)
232      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
233    
234    checkpoint57c_post
235    o Change testing option (-ieee) to get closer agreement between g77 & ifort
236    o generate new output.txt files on faulks with g77 & the new -ieee option
237    checkpoint57c_pre
238    
239    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
240      update output.txt of exp. global_ocean.90x40x15
241    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
242      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
243    o add saltFlux(+File) forcing capability with periodicExternalForcing
244    o allow to use pkg diagnostics for GM-Redi & ThSIce output
245    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
246    o improvements for the MNC output from DIAGNOSTICS:
247      - correct handling of the unlimitied dimension
248      - all dims now have associated coordinate variables
249      - variables located at U, V, and Corner ("Z") points are now written
250        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
251        *all* data points are output
252    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
253    o added pkg/seaice/seaice_monitor.F
254    o mdsio_readfield.F can now read files visible only to master MPI process.
255    o pkg/seaice: some test code for ice-modified ocean stress
256    o exf_getffields interpolation defaults to bilinear for all scalar forcing
257      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
258      spurious negative numbers for precipitation and humidity.  Will cause
259      some small numerical differences for integrations using pkg/exf/exf_interp.F.
260    o pkg/ctrl/
261      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
262        May be enabled via doPackDiag
263      *  introduce z-scaling of
264         + gradient (doZscalePack) and
265         + control (doZscaleUnpack)
266    o pkg/mdsio/
267      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
268      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
269    
270    checkpoint57b_post
271    o simplify options in diagnostics_fill arguments (remove weird combinations)
272    o fix MNC coordinate variables so that they now contain per-face index
273      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
274      general, EXCH2 grids are only aligned to a "local" coordinate system
275    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
276    o Implement instantaneous output within pkg diagnostics:
277      setting a negative frequency in data.diagnostics produces
278     "snap-shot" output (as opposed to time-average if freq > 0)
279    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
280      NOTE: change ptracer diagnostics name: use 2 characters to work with
281            more than 9 tracers. Add also diagnostics of advect & diffus flux.
282    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
283      becomes the coordinate variable for the 'T' dimension
284    o add CF-style coordinate variables to MNC
285      - just a first cut:  numbers are meaningless on the cubesphere and
286        missing along the T axis but otherwise it works!
287    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
288    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
289    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
290      this is based directly on what the model compute, so that the content of
291      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
292    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
293    o clean up build options files for SunOS, in particular
294      - remove -traditional from xmakedepend
295      - change -xarch=v9 to -xarch=native for f77
296      - restore use of make (not gmake)
297      - add CC=gcc if using g77
298    o changes per discussion of AM, JMC, & EH3 today:
299      - move redundant "grid" variables out of "state" -- in preparation of
300        creating proper CF-style coordinate variables and in recognition
301        that any/all grid variables can be easily copied (eg. w/NCO) from
302        the grid files into any of the other NetCDF files
303      - *always* output grid variables with MDSIO (this will eventually be
304        changed)
305      - output MNC grid file if useMNC is true
306    o every instance of _END_MASTER() has been found and replaced with
307      _END_MASTER( myThid ) in order to satisfy certain picky Sun
308      preprocessors
309    o re-arrange diagnostics pkg initialisation:
310     - allow each package to extend the available diagnostics list
311     - add some checking and fix small problems (multi-threaded, ...)
312     - new S/R diagnostics_fill (replace fill_diagnostics):
313       look through the short list of active diag. (instead of the long list)
314       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
315    
316    checkpoint57a_post
317    o this set of changes restores TAMC compatibility
318      tested for global_ocean.90x40x15 adjoint on trough
319      (what a pain)
320    
321    checkpoint57a_pre
322    o some modifs in tools/build_options for sunos
323    o call ctrl_pack for ctrl at end for optimcycle=0
324    
325    checkpoint57
326    o add horizontal bi-harmonic viscosity for vertical velocity
327      - new parameter viscA4W (defaults to viscA4)
328      - affects only non-hydrostatic code
329      - to be done: no-slip lateral boundary conditions
330    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
331    o implement Implicit Vertical advection for pTracers
332    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
333      (implemented also for implicit vertical diffusion & advection)
334    o OBCS: extend application of tracer open boundary conditions
335      to a strip beyond the boundary of width Olx/Oly
336    o add call monitor to TAF set of required calls (flow directives)
337      and include in natl_box_adjoint
338    o untangle a few ifdefs related to cost, ctrl, autodiff
339      untangel a few ALLOW_ECCO_OPTIMIZATION
340    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
341      (theta2, salt2 in ecco_cost_weights)
342    
343    checkpoint56c_post
344    o OBCS as control variables
345      - update ctrl_ad_diff.list, obcs_ad_diff.list
346      - remove balance of obcs controls from default
347      - fix index bug nobcs in ctrl_init
348      - fix dummy fields filen in ctrl_pack
349      - add dummy weights for obcs
350    o lsopt: comment out fort.94 output
351    o optim:
352      - remove unnecessary header files
353      - adjusted namelists
354      - add xerbla.F to Makefile
355    o exf:
356      - multiple modifications of exf_check_range
357      - unit change in exf_init_runoff from [m/year] to [m/s]
358    o mdsio:
359      - i/o-vector change debugLevel from debLevA to debLevB
360    
361    checkpoint56b_post
362    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
363      is called from DO_THE_MODEL_IO
364      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
365      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
366      - clean up PTRACERS_WRITE_TIMEAVE a little
367    o add another verification experiment that tests both the cfc-pkg and
368      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
369      reactive tendencies treated inline with regular timestepping
370    o testreport previously did a lousy job of comparing small numbers, so
371      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
372      implemented in the little c-progam tmp_cmpnum.c which is embedded in
373      testreport.
374    o ptracers_monitor: bug fix for MPI
375

377    o GCHEM: finish reorganizating the package
378      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
379        (introduces another 3D-array for each passive tracer, but only if
380        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
381        gchemTendency is not needed because the timestep is done separately)
382      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
383      - GCHEM is now---more or less cleanly---separate from PTRACERS
384      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
385        so clear to me how that should be done in a general way.
386    o CFC: improve formatting of output in CFC_ATMOS
387    o PTRACERS:
388      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
389        that ALL experiments with ptracers enable can be checked. This makes
390        GCHEM_MONITOR obsolete.
391      - include a runtime parameter PTRACERS_monitorFreq that defaults to
392        monitorFreq
393      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
394    o add PTRACERS (PTR0[1-5]) to testreport output
395    o exf_check_range:
396      * default changed to .TRUE.
397      * will check values for niter0 if debLevA, every timestep if debLevB
398      * STOP in exf_check_range if 'out of range'
399      * range chosen generous to allow for potential extema
400      TBD: a version with stricter range
401           permitted range would be runtime parameters
402  o GMredi:  o GMredi:
403    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
404    - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.    - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.

410      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
411        this flag is now only visible within GCHEM-pkg routines.
412      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
413        be replaced by a 3D array that is computed before thermodynamics; for
414        this, the tracer ID iTracer had to be included into the parameter list
415        of ptracers_forcing
416      - set up forward_step to call gchem_forcing, that will replace
417        gchem_forcing_int in ptracers_forcing
418      - cleaning up
419  o small cleaning of exch2: remove files that are also in eesupp/src  o small cleaning of exch2: remove files that are also in eesupp/src
